Pacemaker lead locking mechanism
First Claim
1. An implantable electrostimulation device with a top portion for the electrical connection of an electrode lead with a fixedly installed connecting socket, the inside wall of which has radially inward pointing contact and holding means for engaging with an electrode lead contact wherein the contact and holding means are formed by a plurality of cam and projection regions that are tightly connected to the inside wall or shaped from it and which are respectively at at least one of a fixedly predetermined angular distance in a circumferential direction of the socket and an axial distance of the socket, the contact and holding means being in a form-locking and a frictional engagement with respectively arranged and formed regions that are formed as part of a pin or annular contact of an electrode lead.

Abstract
An implantable electrostimulation device and an electrode lead is devised ere for the electrical connection of the electrode lead, the top portion of the electrostimulation device has a securely installed connecting socket with radially inward pointing contact and holding devices on its inside wall, which are designed to engage with the electrode lead contact. The contact and holding means are formed by a plurality of cam and projection regions that are securely connected to the inside wall or formed out of this wall and are each at a predetermined angular distance in a circumferential direction of the socket. The electrode lead has a pin or annular contact for inserting into a connecting socket of the electro-stimulation device, which has radially outward pointing contact and holding units on its surface for engaging with the connecting socket. These units are formed by a plurality of cam or projection regions that are securely connected to the surface of the pin or annular contact or are formed from it and are located at a fixed, predetermined angular distance in circumferential direction of the pin or annular contact.
